Those Across the River

Plot Summary:

An adaptation of "Those Across the River," a novel by Christopher Buehlman. The book is described as follows:
Failed academic Frank Nichols and his wife, Eudora, have arrived in the sleepy Georgia town of Whitbrow, where Frank hopes to write a history of his family's old estate-the Savoyard Plantation- and the horrors that occurred there. At first, the quaint, rural ways of their new neighbors seem to be everything they wanted. But there is an unspoken dread that the townsfolk have lived with for generations. A presence that demands sacrifice.
It comes from the shadowy woods across the river, where the ruins of Savoyard still stand. Where a longstanding debt of blood has never been forgotten.
A debt that has been waiting patiently for Frank Nichols's homecoming...
